Plans are described for creating a Graduate Record Examination (GRE) test for the STEM (science, technology, engineering, and mathematics) disciplines. Previous work showed that a quantitative measure for the STEM disciplines exacerbated group differences beyond those reflected in the current GRE General Test. A test development approach is described that links the development of the GRE STEM as an admissions test with the development of a learning scaffolding that will describe the skills assessed in the new measure. This learning scaffolding can be used with undergraduate students to help prepare them for the GRE STEM, thus making the test an assessment both "of" and "for" learning.
